7. O communications protocols e The Remote Master protocol RM NET is the same protocol used by the D4 RM and D4 RS DL405 Remote Master and Slave and the built in ports on the DL250 DL350 and DL450 CPUs This means that the remote O bases connected to a D2 RMSM in a DL205 CPU base can be a combination of D2 RSSS and D4 RS DL405 Remote Slave modules Also the DL405 series CPUs can use DL205 remote bases as remote I O for cost and space savings RM NET does not support the use of the built in communications port on the slave unit e The Slice Master protocol SM NET is the same protocol used by the D4 SM and D4 SS DL405 Slice Master and Slave units This means that the DL205 series can take advantage of the Slice I O features by using a D2 RMSM Master connected to D2 RSSS and or Slice Slave units up to the maximum allowed number of remote units and I O points as well as operate at a higher baud rate Also the DL405 Slice Master can use DL205 remote bases as slaves This protocol supports the built in RS 232 communications port on the D2 RSSS Q D 24 3 Co op D gt D a A remote master resides in the CPU base Depending on the protocol selected this master D2 RMSM controls up to 7 remote slaves RM NET or up to 31 remote slaves SM NET Tt a SY Ly Ja Se Remote Master The D2 RMSM master modules can be used with the DL240 up to seven master

10. the CPU Updates Remote I O Points The CPU and remote master work together to update the remote I O points Below is an example showing how scanning and updating takes place Notice that there are two independent scan cycles occuring at the same time but asynchronously The CPU module is doing its scan which includes looking at the information that the remote master is writing to its internal buffers During every CPU scan the CPU examines the internal buffers of the remote master and updates input and output data from the remote I O It is very possible for the CPU to be scanning faster than the remote master can do its scan It is largely dependent on the size of the application program the baud rate you have selected for the data transfer between the slaves and master as well as the number of I O points being monitored Therefore if you have I O points that must be monitored on every CPU scan it s a good idea to place these critical I O points in the local base The CPU reads the status of any input points associated with remote I O and stores the status in the input Remote Scan y CPU Scan image register Asynchronous to CPU scan A a Mapped into memory using your RLL Read Inputs The Remote Master obtains 0000 40600 octal 0004 0008 bed the I O status from the Remote Slaves Read Inputs from Remote I O c2 ci co 00101100 ON OFF OFF nput Image Register Starting Address
